| 摘 要： | 对温敏不育系滇寻一号S主要繁殖技术与产量作相关分析的结果表明:自交繁殖产量与抽穗期的温度呈正相关;与栽插密度(在100万苗/hm2以内)呈正相关;与氮肥施用量呈二项正态分布;提出在云南元谋的环境条件下繁殖以6月8日抽穗、密度100万苗/hm2,底肥450 kg/hm2碳酸氢铵,栽后 7 d施尿素150 kg/hm2为最好。

| Abstract: | Correlation analysis between growing factors and yield of a TGMS line,Dianxun 1-S suggested that the yield resulted from selfcross of Dianxun 1-S was positively correlated with the planted density below 1.0 million seedlines/hm 2,and positively correlated with temperature at heading dates. It is also indicated that the yield and nitrogen amount had a relation of quadratic equation. The paper proposes that high yield at yunmou can be got by using the following conditions:heading at June 8th,planting 1.0 million seedlings/hm 2,using 450 kg of NH 4HCO 3,600kg for base fertilizers, and applying 150kg of urea per hectare after transplanted 7 days. |
